String

Concatenation operator
<?php
$a = "a";
$b = "b";
echo $a . $b; // ab// concatenation of its right and left arguments
Concatenating assignment operator
Unlike many other languages (+ in Java), PHP has a special operation that can be used to concatenate two strings
together.
<?php
$a = "a";
$b = "b";
echo $a .= $b; // ab// appends the argument on the right side to the argument on the left side
It is important to remember that this is the only way. Using the addition operator (like in Java) will result in the two strings
being first converted to numeric values, and then added together.
<?php
$a = "a";
$b = "b";
echo $a += $b; // 0
